Reagent system NaBH4—ZnCl2 was found to be suitable for the reduction of various substituted quinoxalines to obtain corresponding 1,2,3,4-tetrahydro derivatives. The reduction proceeds quickly under mild reaction conditions. The procedure is convenient and can be applied for a wide scope of substrates.
The present teachings relate to organic semiconductor formulations including an organic semiconducting compound in a liquid medium, where the liquid medium includes (1) a compound in liquid state that has electronic properties complementary to the electronic structure of the organic semiconducting compound and optionally (2) a solvent or solvent mixture for solubilizing the organic semiconducting compound. The present formulations can be used as inks in the fabrication of organic semiconductor devices.
